Win7 system computer upgrade memory to pay attention to what?

            
First, the necessity of memory upgrade
Memory has a well-known impact on the overall performance of the desktop, while the notebook computer's memory is mostly shared mode while burdening memory, memory and other storage functions, so compared to laptop memory The impact of the performance of the whole machine is more significant,
As the software capacity continues to increase, the version is constantly upgraded, and at the same time, the system performance is put forward higher requirements. In the past, the mainstream 1G memory configuration of notebook computers is increasingly unable to To meet our needs, especially when performing image processing, there may even be insufficient memory. Therefore, it is necessary to upgrade the memory.
Second, the memory upgrade needs to consider two factors
Upgrade laptop memory and upgrade desktop memory there are some differences, pay attention to the following 2 points:
1, volume
due to laptop integration The design is precise, so try to choose a relatively small memory module under the same capacity, which reduces the chance of collision with other accessories when inserting the memory, and the smaller memory can avoid the electromagnetic interference between the accessories. It is also more conducive to heat dissipation, thus ensuring the stable operation of the notebook.
2, capacity
For the pursuit of small size, the memory slot of the notebook is limited, most laptops have two 144-line DIMM slots, the upgrade space is limited, in order to avoid In the future, memory capacity will become a bottleneck affecting performance. It is recommended to select a single memory with a larger capacity. In addition, the memory with a smaller number of chips has a lower heat generation value under working conditions.
Third, memory algebra: Now the memory has been developed for many generations, the mainstream memory is DD3, if you want to add memory, then you need the same model as your computer, or else it can not match.
